How are the lytic and lysogenic cycles similar and different in terms of process and infection?
ELEN [110]

Answer:

<h2>Lytic cycle: involve that there is rupture( lysis) of the host cell and release many copies of virus. </h2><h2>Lysogenic cycle:  involve the insertion of the nucleic acid of a bacteriophage into host genome, known as prophage. </h2>

Explanation:

There are many  similarities and differences between lysogenic and lytic cycles that;

1. Lysogenic cycle of bacteriophage :

i)  in lysogenic cycle:  bacteriophage insert its DNA with that of a host, known as prophage and it replicates with host.

2. Lytic cycle of bacteriophage:

i) lytic cycle is that it results in many copies of the virus very quickly and the cell is ruptured and many copies of virus are released.

4. Similarity is that in both cycles bacteriophase inter into the host and use their machinery.

Describe what needs to occur in order for a metamorphic rock to form.
katovenus [111]

Answer:

Any sort of prexisting rock whether sedimentary, igneous, or even metamorphic rock must change under extreme conditions like extreme heat or pressure.

Explanation:

An igneous rock is a rock that has been created via cooling of magma.

A sedimentary rock is formed from sediments, whether they be natural like seashells, or other pieces of older rocks that have worn away. usually formed under pressure.

A metamorphic rock is a rock that's changed, because it was put under extreme pressure or exposed to extreme heat.

Think of the part morphic in the word metamorphic-it literally means that it morphed or that it changed dramatically.

There are two ways for a rock to become metamorphic under <u>extreme pressure</u> or <u>extreme heat</u><u>.</u> and there are two types of metamorphic rocks, <u>contact</u> <u>metamorphism</u> and <u>regional metamorphism</u><u>.</u>

Those mean pretty much exactly what they say.

If you have any more questions, ask, but i think I covered the most important parts of the answer.

best of luck

HELP ASAP!! Which atom is present in everything that is alive or ever was alive? Provide facts.
gregori [183]

Carbon is the atom, which is necessarily find in the living organism.

All the living organisms are made up of biomolecules. All the biomolecules are organic compounds. The substance cannot be consider as living, if it lacks nucleic acids. There are two types of nucleic acids DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), both have a structure made up of carbon rings and chains.

Other than nucleic acids, proteins, enzymes, hormones etc are also made up of carbon. So, all the living cells, or dead remain of organism must have carbon atom.

Hence, the correct answer is option D. carbon.
